User-oriented, secure, trustful & decentralised social media

Deliverables

Human-as-trust-sensor and reputation mechanism

This deliverable will consist of two phases, starting with the development of user content verification efficacy models (using a range of machine learning algorithms) which extract user activity attributes in real-time (ethically and autonomously in alignment and adherence to approaches defined in D.3). This user modelling phase will then be followed by a second phase (M14) which will integrate the initial Human-as-trust-sensor efficacy models with the EUNOMIA blockchain (D3.4) to extract historic user content verification records (e.g., performance and activity) to generate an ensemble reputation calculation mechanism. The human-as-a-trust-sensor reputation mechanism will then be embedded as an autonomous software module activated via a verification reporting function in the Digital Companion (D4.3).

Social media content and context data collection and analysis - update M28

This deliverable will have two phases An initial version produced for the first integration prior to pilot phase Alpha and an updated version based on the evaluation of this phase It includes definition of data processing pipeline and development of core processing modules advancement of core modules and development of a suite of content processing tools as well as adaptation of tools and packaging of the anonymised data meant for being shared with the scientific community

Trustworthiness scoring

This deliverable has two phases (M14, M28): The first will focus on allowing the fusion of information from the reputation mechanism and confidence scores from the content and context data collection and analysis, enhanced by autonomous data extraction using datamining techniques.

Each component will be an embedded trustworthiness scoring software module in the Digital Companion (D4.4). This component will be designed to draw on both components’ output with a developed objective majority-vote algorithm calculated locally on the Digital Companion. The final version will involve the improvements carriers out following the first phase of pilot evaluations with real users.
